Upgrading from starter edition to full version.

Hi. I started the RAF thing with my friend today. She got a "Starter Edition" account and she bought the retail game and now she wants to upgrade her account to a full version wow account but when she clicks Upgrade her only option is to buy the game. how does she upgrade her account if she already bought the game and has a key to upgrade?

1 more question. she has 2 starter edition accounts. she made her wow1 SE account when she wanted to try the game. and then the wow2 SE account when we started RAF. if she puts the CD key into that "Enter Code", will she be able to choose which of those 2 accounts she wants to upgrade?

Well, how do she know what account she upgrades? can she like delete the wow1 account that she doesn't need anymore? Because she can't choose to which account she wants to enter the CD key because she can only put the Code into that Enter Code box after she clicks "Upgrade a Game" and when she clicks her wow2 account she can only upgrade by buying the game online, there is no place where she puts the CD key.

Hi, i got the starter edition game and i upgrate it few min later but even if on my account information i got the active account status with Cataclysm on it while i'm on the game i got the message that started accounts cannot use this or that... any ideas why this happened?
